Figure 5. Two-dimensional distribution of the principal coordinate analysis (PCoA) for CC₅₀, CC₉₄ and OWGB Marrakech.

Colours indicate the three gene pools (eastern, western and central Mediterranean Basin). The genetic variation of each principal coordinate (PCo1 and PCo2) is indicated. Both core subsets span the range of all genotypes among the three gene pools, whereas the majority of entries were found to occur in the central Mediterranean area.
